VALVE-LOCKING ATTACHMENT.

Application filed April 27, 1927. Serial No. 187,095.

This invention relates to cock-locl ing attachments for gas ranges and is particularly adapted to that type used in connection wlth gas burner systems.

The principal object of the inventlon is to provide a simple and efficient devlce of this character which may be readily attached to any gas cook so as to lock a turning plug 1n closed position against accidental rotation.

Further objects of this invention w ll appear as the following specific description is read in connection with the accompanying drawing, which forms a part of this application, and in which,-

Figure 1 is a plan. view of the attachment as applied;

Fig. 2 is a section through line 2-2 of Fig. 1;

Fig. 3 is a section through line 3-3 of Fig.1;

Fig. 4 is a section through line 4-4: of Fig. 1.

Referring more particularly to the drawing, numeral 1 designates the handle. of the conventional gas cock. A pair of clamp elements 13 are clamped about the gas feeder pipe 12, by means of the bolts and nuts 10, and are provided with flanges 7 and 8, which extend laterally of the clamp to the rear of the pipe 12.

The flanges 7 and 8 are provided with a pair of apertures to receive a pair of slidable rods 9 with which there is integrally cast a handle locking member 4. The locking member is held normally in an elevated position by means of a pair of springs 5 which surround the rods and are positioned be tween the upper flange 7 and the member 4. The member t is restrained in the extent of its upward movement by means of nuts and screwed on the lower ends of the rods'9. The position ot'the nuts on the rods obviously determines the locking tension of the springs 5. The upper surface of the memher 4 is grooved at 3 to provide a recess moved down against the tension of the springs unt1l the handle reaches the groove 3. At this stage of the movement the springs become released and force the member about 'the handle to lock the same closed.

In order to open the valve the member 4 must be lowered against the pressure of the springs until the handle is free of the groove 3. The handle may then be freely moved to the open position. This operation may be accomplished by pressing down on the surface 6 with the thumb and then turning the handle with the forefinger as the thumb holds the locking member in the lowered position.

It is self-evident that the construction shown in the drawing is not by any means to be construed as limiting my invention to the present design. It is understood, therefore, that improvements and changes may be made without departing from the broad scope of my invention which I wish to cover by Letters Patent and for which I claim.

Having thus described the invention, what is claimed is: I

A locking attachment for gas cocks, comprising a clamp, a reciprocating handle engaging element slidably mounted in said clamp, and separate means for resiliently holding said element in an upwardly extended position, whereby said element may engage and lock the handle in closed position.

In testimony whereof, I aliix my signature.

JAMES BALZANO.
